StackDriftInformation

Structure Class

StackDriftInformation dataclass

Bases: _SerdeShape

Contains information about whether the stack's actual configuration differs, or has drifted, from its expected configuration, as defined in the stack template and any values specified as template parameters. A stack is considered to have drifted if one or more of its resources have drifted.

Attributes

last_check_timestamp class-attribute instance-attribute 
last_check_timestamp: datetime | None = ...

Most recent time when a drift detection operation was initiated on the stack, or any of its individual resources that support drift detection.

stack_drift_status class-attribute instance-attribute 
stack_drift_status: str | None = ...

Status of the stack's actual configuration compared to its expected template configuration.

  • DRIFTED: The stack differs from its expected template configuration. A stack is considered to have drifted if one or more of its resources have drifted.

  • NOT_CHECKED: CloudFormation hasn't checked if the stack differs from its expected template configuration.

  • IN_SYNC: The stack's actual configuration matches its expected template configuration.

  • UNKNOWN: CloudFormation could not run drift detection for a resource in the stack.
